Love this project. But get unexpected errors.

[venturaEffect]

Love it! Really!

But when trying to make it work it is strange because the error messages are too generic and doesn't explain much to help me solve it.

For example one is that I get the error message:

"An error was encountered. Try reducing your similarity top K or chunk size."

When I put the top_k to 1 and chunck_size to minimum it still appears this error message and doesn't work. When trying to tweak other things it just redirects me to the first page with an error message of password incorrect. Even if password is the same set on settings.csv and on secrets.toml

I pretty use as default to avoid behaviours I can't figure out when starting but still. The errors appears by trying to test it.

Another thing is that it takes long time to be able to run the model. Always when trying to start the chat it holds loading saying "Initializing".

I know this is a massive work to document everything, and honestly the readme file is pretty good. But there are many things like error handling that isn't clear enough (at least not for me) and would appreciate A LOT your help.

Appreciate your effort and your time.

[dhopp1]

You're absolutely right, it is opaque what the error is in that message. The reason it's a relatively unspecific message is that it is for users not developers, and those two actions (reduce top k, reduce chunk size), are the only two things a user can do that would fix an error. When I had it return the full message users would get intimidated and tell me it was broken and not try that fix even if that was the issue. On my part as the developer, if it was broken for a different reason (usually out of VRAM or LLM didn't load properly for some reason), I could see that in the back end on the server and didn't need it to print in the application.

You can have it return the full error message by editing line 865 of helper/ui.py, from:

except:
    st.error(
        "An error was encountered. Try reducing your similarity top K or chunk size."
    )

to:

except Exception as e:
    st.error(f"An error occurred: {e}")

Thanks a lot for answering.

What about when it redirects to the login page with a message that the password is incorrect when I was just trying to select a different model or testing the other settings? It is weird because the password is the same and fi I'm not wrong there is no security filter when trying to change the settings on the interface.

And the other thing is that it takes long time to be able to run the model or when uploading files. Also when trying to start the chat it holds loading saying "Initializing". Is there a way to avoid this?

Again, thank you a lot for sharing this amazing work and for thaking your time reading the issues (it seems only me has issues :( )

[dhopp1]

More details would be helpful in diagnosing your problem. What's the system you're running it on? A mac? Windows? Windows with docker? GPU? etc. Have you ever gotten it to work? Or does it just go to initializing and never do anything from there? Or it comes up but only after a very long time. Are you sure you have enough VRAM to load two models at the same time? If not check the clear other LLMs on reinitialize box under advanced model parameters.

Also have a look at the terminal where you launched the application from, whether that's the docker compose window or the streamlit run app.py window. That will give you more information on what's happening behind the scenes when those errors pop up.

[venturaEffect]

Yes,

1. I have a Windows 11 with an NVIDIA RTX 4090 16 GB VRAM.
2. I've gotten it to work. But it kicks me all the time to login and tells the Password is incorrect even if the password is the same and there is no other security steps. The other thing is that even trying to login again, it doesn't work. I do have to refresh and login.
3. Always at the beginning it stays with "Initializing... " and it takes forever. I refresh the page what kicks me again out to login and then it seems to be loaded.
4. When trying to Upload files it also takes long time and when clicking in process corpus it kicks me again out.
5. When checking "clear other LLMs on reinitialize" it just stays with "Initializing... " without making any changes.
6. This is one error message I've got when clicking choosing other LLM:

BTW, I'm using the default settings and just added one more LLM. The funny thing is when just using the mistral-docsgpt, when starting to answer, it talks to itself as they were two. A user and the asisstant. Without me touching anything.

Thanks a lot for your help!

[dhopp1]

Since Llama 3 came out that one is better than mistral-docsgpt. You can download the Q5 quantized Llama 3 chat GGUF here.

In terms of why it boots your session I'm not really sure why that's happening to you, it's never happened to me. Same for taking a long time during initialization. I really need to see the terminal outputs at the moment those errors occur. The one you posted there is just huggingface's warning when loading the embedding model.

Another option is to just try it with Docker, which might fix a lot of these problems since the docker compose file works on a windows PC with a 4060.

Errors or messages on the terminal for streamlit_rag

When login: 2024-06-19 18:06:09.427 MediaFileHandler: Missing file 578af70b83afb82c632d79f9d22cff7d6734e4141709b66ba02f82a0.png model not found, if passing an llm_path, try setting redownload_llm = True When choosing LLM (that are already downloaded on the models folder, no worries, I did it already when installing it manually). There are no errors or anything on the terminal but it kicks me out to the login page and it tells password incorrect (?) Username and password are ok but nothing happens when clicking enter. I have to reload the page again, select the username (the only one there is) and write the password (the same one).

Now pressing the enter button works and opens the interface with the llm from the beginnin. Nothing changed. But now the terminal shows: 2024-06-19 18:06:09.427 MediaFileHandler: Missing file 578af70b83afb82c632d79f9d22cff7d6734e4141709b66ba02f82a0.png model not found, if passing an llm_path, try setting redownload_llm = True 06/19/2024 06:10:19 PM - Load pretrained SentenceTransformer: sentence-transformers/all-MiniLM-L6-v2 C:\Users\zaesa\anaconda3\envs\streamlit_rag\Lib\site-packages\huggingface_hub\file_download.py:1132: FutureWarning:resume_downloadis deprecated and will be removed in version 1.0.0.

Again, when trying to choose another model (mistral-docsgpt) it kicks me again out. And no error message or anything on the terminal.

After login again I don’t touch llms as it always kicks me out and go to add files. Add one .txt file and click process corpus. The terminal shows again: 06/19/2024 06:13:25 PM - Load pretrained SentenceTransformer: sentence-transformers/all-MiniLM-L6-v2 06/19/2024 06:13:27 PM - 2 prompts are loaded, with the keys: ['query', 'text'] The interface stops at:

(2/7) converting to text: 1/1 Initializing...

And nothing happens.

Deleted and loaded back again the llm_list.csv as it is in the repository. No other llm.

Login. The interface doesn’t show the input where to write to the llm. Load again. Login.

Now it stays “Initializing… “ again forever without any changes. All settings are as default on the interface. Just mistral-docsgpt as llm.

BTW, this is what it shows on the terminal: 2024-06-19 18:18:00.689 MediaFileHandler: Missing file 578af70b83afb82c632d79f9d22cff7d6734e4141709b66ba02f82a0.png 2024-06-19 18:18:00.815 MediaFileHandler: Missing file 578af70b83afb82c632d79f9d22cff7d6734e4141709b66ba02f82a0.png llama_model_loader: loaded meta data with 25 key-value pairs and 291 tensors from models/docsgpt-7b-mistral.Q6_K.gguf (version GGUF V3 (latest)) llama_model_loader: Dumping metadata keys/values.

Now it doesn’t even load. Weird because it shouldn’t be a problem by loading the model because it is already downloaded on the models folder. And I have VRAM enough.

And this would continue. Sometimes I get the model to run but it sarts to talk to itself like they were two personas.

And I haven't touch the system prompt or anything as template to use the llm.

Appreciate a lot your effort. It can surely be some silly thing that I've done wrong. But I thinik I've done it as it is in the README.md and without changing much on the settings.

Thanks!!

[dhopp1]

Hm there's a lot going on here. Why don't you break it down and test component by component. In this case, I would try and see if you are able to run local_rag_llm by itself without issue. I would do:

1. test local_rag_llm by itself without RAG, see if you are able to get sensible responses, chat/contextual memory, etc.
2. if that works, now test it with RAG with a simple .txt file
3. if that all works with no problem, then you can move to the streamlit issues

If you're still having a lot of issues I would give it a shot with Docker, it might take you less time to just set that up than to troubleshoot on the local installation.

[dhopp1]

Another thing you can do to just stop the getting kicked out issue is just change the check_password() function in user_management.py (line 23), to simply return True.

[venturaEffect]

You mean to download the local_rag_llm separate and to test it? And download Postgresql and pgvector?

The issue with Docker is that I want to make it pretty straight forward to a friend. So he doesn't get lost as hedoesn't have much knowledge.

My idea is to pack all the comandlines and installation on one file .bat .sh and by clicking make the installation and run.

[venturaEffect]

Maybe I did have to install on streamlit_rag also the packages that are on local_rag_llm? I've seen also when installing streamlit_rag that there were a lot of packages that weren't on the requirements.txt file of streamlit_rag and was always a message on the terminal of missing it. And I mean reaqlly a lot: psutil streamlit streamlit-server-state tabulate llama_index llama-index-llms-llama-cpp llama-index-vector-stores-postgres llama-index-embeddings-huggingface PyPDF2 pdf2image textract langdetect spacy wordfreq bertopic seaborn wordcloud six

[dhopp1]

Ah OK that maybe explains a lot, including getting kicked out of the application saying wrong password etc. If you're installing directly, this line in the README is important:

The LLM and RAG system relies on two key libraries you should set up and make sure are working independently: nlp_pipeline for the processing of documents local_rag_llm for the LLM itself

I would do that, make sure all those dependencies are installed, then try again. That includes installing postgres and pgvector from local_rag_llm. I'm surprised you even got any responses whatsoever without doing that.

Regarding the .bat file and your friend, I see. Though that's kind of exactly the idea with Docker. It's probably simpler to tell them, install Docker, clone this repo and run docker compose up. But if you can figure out how to do it all with a .bat file, I agree that's simpler for a non-technical person. So if you do manage to get that working please do share it with me, it could be helpful for others. You can use the Dockerfile as a guide to see exactly what's necessary and what steps lead to a working installation, though you'll have to tweak it a bit from Linux to Windows.

[venturaEffect]

I see now.

I I got both from installing them and of course there were no requiments.txt so I wasn't aware of it.

Let me look if now I get it through.

Also, if I figure out how to do it to work directly by just clicking on a .bat file will share it with you.

In any case, thanks a lot!

[venturaEffect]

Now I get no error messages. The thing is that the first time it is loading there is no input to write to the chat. I must load again but the loading time takes forever. It holds on "Initializing... ". I must refresh the website three times to get the input field.

Now it doesn't kick me out as before, when clicking any button, but the LLM (mistral-docsgpt) has weird behavior like talking to itself as they were two.

I've included another LLM on the llm_list.csv, and when trying to use it but takes exceptionally long time, but this one seems to answer properly. I thought they made be a problem in the System prompt or on the template for answering the LLM, but having the same settings can't figure out what is the cause one mistral-docsgpt acts like they were two talking to each other and the other not :D.

BTW, the other LLM I'm using is: https://huggingface.co/bartowski/Llama-3-8B-Instruct-Gradient-1048k-GGUF/blob/main/Llama-3-8B-Instruct-Gradient-1048k-Q5_K_S.gguf Has a long context windows what I think is great for this use case.

[dhopp1]

LLM/GGUF compatibility depends on llama.cpp, for instance Llama 3 was doing this too before llama.cpp was updated with the right stop token for that model family, it would just keep going as you describe until the max token limit was reached. I haven't used mistral since Llama 3 came out, but I never had that issue when I was using it. Also sometimes it does this when it is running low on VRAM or if it's asked to generate two outputs at once, why I have no idea.

Back to why it takes forever on initializing, I'd go back to testing local_rag_llm on its own first, then back to streamlit. I've never had the initializing step take long on any of the OS's or installations I've done, but that step is all about setting up the local_rag_llm model object.
